Claims (3)

1. A torque converter for motor vehicles comprising a housing, a bridging clutch and two dampers, a radially inner damper and a radially outer damper, the dampers being located in the housing, wherein the bridging clutch is positioned in the power path between the inner and outer dampers, wherein an outer disk support of the bridging clutch is directly attached to an output part of the radially outer damper and an inner disk support of the bridging clutch is connected to an input part of the radially inner damper in a rotationally fixed connection, wherein springs of the outer damper are engaged with an axially extending portion of an input part of the outer damper, the output part of the radially outer damper being a one piece element having an S-shape and a curve on the radial outer area engageable with the springs of the outer damper, the output part of the radial outer damper following a curved contour of the housing and wherein the converter has a three-duct system for the oil supply, wherein the input part of the radially inner damper is non-rotatably connected to an additional input element, the additional input element being non-rotatably and directly connected to a turbine.
